Detailed explanation-1: -The state cabinet of Uttar Pradesh chaired by its Chief Minister Yogi Adityanath recently approved the Groundwater Act, 2020. The act aims at improving the falling groundwater level of the state.

Detailed explanation-2: -The correct answer is Tamil Nadu. The total replenishable groundwater resources in the country are about 432 cubic km. Ganga and the Brahmaputra basins have about 46 percent of the total replenishable groundwater resources.

Detailed explanation-3: -The level of ground water development is very high in the states of Delhi, Haryana, Punjab and Rajasthan, where ground water development is more than 100%. This implies that in these states, the annual ground water consumption is more than annual ground water recharge.

Detailed explanation-4: -Water in the saturated zone below the water table is referred to as ground water. Below the water table, the water pressure is high enough to allow water to enter a well as the water level in the well is lowered by pumping, thus permitting ground water to be withdrawn for use.
